found, wherever compared, to be physically stronger than 
savages. They appear also to have equal powers of 
endurance, as has been proved in many adventurous

If in each grade of society the members weie divided 
into two equal bodies, the one including the intel- 
lectually superior and the other the inferior, there can 
be little doubt that the former would succeed best in 
all occupations and rear a greater number of children. 
Even in the lowest walks of life, skill and ability must 
be of some advantage, though in many occupations, 
owing to the great division of labour, a very small 
one. Hence in civilised nations there will be some 
tendency to an increase both in the number and iu 
the standard of the intellectually able. But I do not 
Wish to assert that this tendency may not ho more than 
counterbalanced iu other ways, as by the multiplication 
of the reckless and improvident ; but even to such as 
these, ability must he some advantage. 
It has often been objected to views like the fore- 
going, that the most eminent men who have ever lived 
have left no offspring to inherit their great intellect.
